Experimentation is important when designing communication protocols forWireless Sensor Networks. Lower-layers have a major impact on upper-layerperformance, and the complexity of the phenomena can not be entirely capturedby analysis or simulation. In this report, we go through the complete process,from designing an energy-efficient self-organizing communication architecture(MAC, routing and application layers) to real-life experimentation roll-outs.The presented communication architecture includes a MAC protocol which avoidsbuilding and maintaining neighborhood tables, and a geographically-inspiredrouting protocol over virtual coordinates. The application consists of a mobilesink interrogating a wireless sensor network based on the requests issued by adisconnected base station. After the design process of this architecture, weverify it functions correctly by simulation, and we perform a temporalverification. This study is needed to calculate the maximum speed the mobilesink can take. We detail the implementation, and the results of the off-siteexperimentation (energy consumption at PHY layer, collision probability at MAClayer, and routing). Finally, we report on the real-world deployment where wehave mounted the mobile sink node on a radio-controlled airplane.
